To process this page used the WaterSteamPro function "wspCPSTX": specific isobaric heat capacity in double-phase area [J/(kg·K)] as function of temperature t [K], vapor fraction x [-].
Function uses functions wspCPSST and wspCPSWT which return specific heat capacities at constant pressure (Cp) of steam and water at saturation line. The function uses following formula: CPx = (1 - X)·CPw + X·CPs, where CPs = wspCPSST, CPw = wspCPSWT and X - vapor fraction. The range of calculation is double-phase (water-vapor) area.
